So on the proportioning valve knob it says one direction to increase and the other direction to decrease the pressure. I'm a bit confused and would like some clarification on this, if I want to have the rear brakes apply a bit more do I decrease or increase the pressure?

The main body of my valve was slightly loose when i got it. Being curious i unscrewed it and the small brass bushing with the teflon washer and spring washer fell out. How does this go back in? I am guessing the teflon side down and the brass bushing towards the spring.
